Abstract
A process is disclosed for formation of a preformed stabilizer for use in formation of graft polyols. The preformed stabilizer has a reduced level of transesterification products and results in less reactor fouling. The preformed stabilizer is prepared in the presence of phosphorous compounds, which reduces the unwanted transesterification products.
